[ DDNS ]
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname,
allowing your computer to be more easily accessed from various location on the Internet.
HWe support free DDNS account and customer pay account. To use this service, for free account,

If DVR is behind Firewall or NAT: Please tick “I am behind Firewall or NAT＂and enter the
Firewall or NAT IP address and Login account information including User name and Password so
that DDNS can adopt this IP address and update it to DDNS provider.
If DVR is not behind Firewall or NAT and DVR connects to network by PPPoE and get IP
address assigned by ISP, then DDNS will adopt this IP address. Otherwise, DDNS will adopt
physical IP address of LAN card which is installed in DVR.
Note:
1. It is possible that the function of auto detecting Firewall/NAT IP address will be affected
by the ISP’s transparent proxy so that DDNS provider detects the wrong IP. Please ask
your local ISP to solve this issue. .
